SWT DI Lights

 

DI Water Quality Monitoring 24/7

Contrary to popular wisdom, water doesn’t conduct electricity very well. The lower the dissolved solid content (TDS), the greater its resistance to the flow of electricity. (Deionized water in its purest state has a resistance of 18.3 million ohms per cm.) In the water business we commonly use electrical resistance to describe the purity of deionized water. But whether the measure of purity indicated by a meter is in ppm, microsiemens, or ohms, it still derives from passing a small current through the water and measuring its resistance.

SWT's DI Lights (pictured above) offer the most efficient means to monitor water quality—the green light indicates the water resistivity is above the threshold value; the red light indicates that it is below. These simple lights come in a wide range of preset values and are available with 1/2 inch MNPT or 3/4 inch MNPT connections. They are an effective and inexpensive way to monitor all but the highest quality deionized water.

Hy-Lite Water Quality Indicator Systems are designed for more advanced high purity applications. Featuring exclusive Auto Temperature Compensation (ATC) and Surface Mount Technology (SMT) circuitry for unequaled accuracy, the Hy-Lite is by far the most precise “quality light” available. With visual green and red indicator lights, an audible alarm option, as well as remote and control capability, the Hy-Lite is also the most versatile product of its kind.
